One of the things that’s always cool to watch at the 24 Hours of Le Mans is the American presence. Here’s a quick primer on the 18 American drivers (4 LMP2, 2 GTE-Pro, 12 GTE-Am) in this year’s race:

David Cheng, Chinese-born but sharing U.S. and Hong Kong residence, makes his 24 Hours of Le Mans debut in the No. 33 OAK Racing Team Asia Ligier JS P2 HPD in LMP2. Cheng is the 2013 Asian Le Mans Series champion and also has a PC class win at the Mobil 1 Twelve Hours of Sebring on his resume.

Matt McMurry and Chris Dyson share the seat of the No. 42 Caterham Racing Zytek Z11SN Nissan (LMP2). McMurry, 16, will set a record as the youngest driver ever to compete at Le Mans and is Dyson Racing’s first Junior Development Driver. Mentor and teammate Dyson returns to Le Mans as a driver for the first time since 2009.

The brothers Ricky and Jordan Taylor, who drive for Wayne Taylor Racing in the TUDOR United SportsCar Championship, are split at Le Mans. Ricky will co-drive the No. 50 Larbre Competition Morgan Judd in LMP2; Jordan is one of two Americans in Corvette Racing’s six-driver lineup, sharing the No. 73 Corvette C7.R.

Former Le Mans class winner Tommy Milner shares the No. 74 Corvette C7.R. He and Jordan Taylor are the only two Americans in the GTE-Pro class.

South African born Mark Patterson races under U.S. nationality and shares the No. 53 Ram Racing Ferrari F458 Italia in GTE-Am.

One of only four U.S.-entered teams, Krohn Racing was a late GTE-Am entrant due to Strakka Racing’s withdrawal and team principal Tracy Krohn is again back in the No. 57 Ferrari F458 Italia.
